Compatible Format(s): Sealed
Like with a normal Sealed event, each player buys and opens a deck before the start of the event. Unlike a normal Sealed event, after all players have opened and registered their decks, each deck is placed on a table. Players are arranged in a random order around the table. The event organizer then randomly selects and calls out a deck. That deck’s owner must start by bidding 0 chains. Then, in clockwise order, other players may bid higher than the current bid, or pass on bidding further for that deck. When all players have passed, the highest bidder wins that deck to use for the duration of the tournament and passes bidding on all other decks. Repeat the process for each deck. If a deck is randomly selected and its owner has already won the bid for another deck, the next player in clockwise order must place the initial bid of 0 chains for that deck.
Players start each game in that tournament with chains equal to their highest bid for the deck they are using. At the end of the event, each deck returns to the person who originally purchased and opened it.
The Sealed format is less appealing to some players because they have little control over the houses or cards they play with. The Auction variant allows players to still have some control over what they use for the tournament. Similar to the Adaptive variant, the bid chains also serve as a balancing mechanic to bring decks in line with each other.
